Bivariate model based image restoration in un-decimated wavelet domain
Cheng Cun · Computer Engineering and Applications Journal · 2007
Regards the Bivairate Probability Distribution Function(PDF) as the apriori distribution of wavelet transform coefficients of natural images,and proposes an image restoration algorithm based on Bivariate distributions of un-decimated wavelet domain from the view of Bayesian theory.Discusses this restoration algorithm from the view of local adaptive regularization.At last,verifies this algorithm through performing experiments with four standard testing images and comparing with other some well-known restoration algorithms.
